It's not recommended to run 2 different antiviruses at the same time. You can install different ones, of course, but only run one the real-time part of one at the same time.
Did you try running a CD-based version of some other program than BitDefender. There are many, they are free, and since you boot from the CD to run it, there is no need to install it, and there's no interference with anything running in Windows.

I have Win 7 running Bit Defender Total Security which works fine. My problem is that I keep getting the same virus repeatedly (it is ID'd by BD and quarantined).
I also run Antimalware bytes, but this refuses to run over half the time (even using their "Chameleon" disguise).
I am considering installing and running Kaspersky's Pure 3.0 2015 along with Bit Defender. Call me a belt and suspenders guy, but security is mandatory and I want to be well-fortified.
Question: Can anyone verify that the two programs will not conflict, either during installation or more importantly, during use? I would like some hard info before I make the purchase of the Kaspersky Pure 3.0. Help please? Much appreciated.
